To all whom it may concern: 7

Be it known that I, MARTIN M. KovAL, citizen of the United States, and resident of leilwood, in the county of Indiana and State of Pennsylvania, have invented certain new and useful Improvements in Station-Indicators, of which the following is a specification.

This invention relates to station indicators for railroad and street cars, and has for its main object the provision of such a device which will accurately and plainly name the next station en route and which is simple in manner of operation and construction. The above and other objects willbecome apparent in the description below, in which characters of reference refer to like-named parts in the drawings.

Referring briefly to the drawings, Figure 1 is a front elevational view of my device as it is mounted in a conspicuous place in a car. Fig. 2 is a sideview of the same, showing the reversing levers.

Fig. 3 is a front elevational View of the same with the'cover removed. 1 Fig. 4L is a side elevational View of the same with the cover removed.

Referring now in, detail to the drawin s, the numeral 1 represents the frame of t e box containing my device, and 2 the cover therefor. Arcuate slots 3 and a are provided as shown on the side of said cover, through which project the handles of reversing levers 5 and 6, presently to be described.

Shafts 12 and 23 are mounted in the side walls of the frame 1, and upon said shafts, in the compartment 33, (the box 1 being divided as shown into two compartments 33 and 24L) drums 7 and 9 are respectively loosely mounted. The drum 7 has a lever 5 attached to its end, and the drum 9 a lever 6. Flat or disk cams 8 and 9 are secured to the wall of the compartment as shown, so that, upon rotation of the levers 5 and 6 in a clockwise direction, the drums 7 and 9, respectively, will be pushed to the right. The disks 7 and 9 are rigid respectively to said drums, and contain in their outside surfaces conical grooves 32. Adjacent said disks additional disks 31 are rigidly mounted to the shafts 12 and 23, one to each. On the side of said disks facing the disks32 are mounted conical projections 34 adapted to engage the conical recesses 32 when the drums 7 and 9 I shoulder.

.1n said pawl'and passes downwardly thereare movedto the rightby operation of the levers 5 and 6; V V 1 In the" compartment 24-. a commontypeof spring coil 1 1 is mounted in a casing 15 upon the shaft 12, a key 16 being provided outside the box 1 for the purpose ofwinding up said spring,[Intermediary shafts 17 etc. are mounted in said compartment between the shaft 12 and the shaft 23, and intermediary gea-r'wheels 13, 20, 18, 19, and 21, etc., are chained between said shafts so as to commu-. nicate motion from theshaft 12 to the shaft 23. 12 and 23 between the disks 7 a and 31, and 99 and 31, respectively, so as to keep said disks normally separated and, the drums 7 and 9 to the left. I The periphery of the upper disk 31 is shaped like a cam'with a shoulder thereon against which rests the beak of a pawl 27. A spring 28 presses against said pawl so as to normally retain the end thereof againstsaid A string 25 is attached to'an eye from through a hole in the box 1.'

An opening 35 is provided in the front cover of the box, above which is printed at 30 some such legend at Next stop is. A tape 11 is'wound upon the drums? and 9 as shown, and upon the face of said tape, at spaced apart intervals, are printed the names of various cities, such as New York and all.

the intervening cities between New York and, say, Chicago, when the device is used on a train traveling between said cities. Now, the cord 25 is placed somewhere in convenient reach of the'conductor, sothat, when the train leavesv a station, he may'pull the cord and immediately release it. By pulling the cord he will have disengaged the pawl 27 from the shoulder in the disk 31 and thus allowed the latter to rotate one revolution, the same being, at the com letio'n of 'said revolution, again stopped y the pawl 27. Now'the levers 5 and 6 were, before this operation and during the same, in the positions shown in Fig. 3 so that the upper disk 31 rotated in a counter clock wise direction, thus winding the tape about the drum 7, and unwinding it from the drum 9, the'latterbeing free to rotate about its shaft 23. The names on the tape are so arranged that, on the stopping of the wheel be presented before the opening 35. On reverse motion of the train, the lever is swung all the'way to the left in the slot 4, disengaging the drum 7 from the shaft 12,

and the lever 6 is swung all the way to the I right in the slot 3, engaging the drum 9 with the shaft 23. Then, when the cord is pulled, the rotation of the shaft 12 caused by the spring 14: is transmitted to the shaft 23 by the intervening gears so that the tape is then wound upon the drum 9 and from the drum 7. V

' of the platforms (on leaving a station) the device will be operated to indicate the next station. I

Having thus described my invention, what -I claim anddesireto secure by'Letters Patent is as follows:

A device of the class described comprising a frame, a cover for said frame, a partition therein dividing said frame into two com partments, a drum mounted in the lower portion of one of said compartments, a sec ond drum mounted in the upper portion 01 the same compartment, shafts upon which said drums are loosely mounted, a clutch on each of said shafts for locking or releasing said drurns upon their respective shafts, a clutch-operating handle extending from each of said clutches and passing out from said frame, the upper of said drums being provided with a notch in the peripher'y thereof, a pawl adapted to releasably engage said notch, a spring normally urging said pawl against the periphery of sai drum, a cord attached to said pawl and passing outward from said frame, a gear mounted rigidly upon the shaft of said first-named druin and located in the other of said compartments, a spring motor adapted to rotate said last-named shaft, a pinion rigid to the shaft of said last-named drum, gears connecting said first-nained gear with said pinion, a tape wound partly upon each of said drums, an opening in said frame, and legends printed on said tape adapted to appear singly behind said opening. 7
